If you will be in this house for a year or two, then moving back to the US, I would say stick with hand tools, excepting perhaps a thickness planer to help with milling. It could be Euro-style powered, and stay behind when you leave, but will save you a LOT of boring work.
Sales photos (ripped from Google) for the visual that address the last comment. The double Wye/Tee combo goes by different names with different suppliers and has a couple of profiles from large radius sweeps to three piece 45° "kinks." Either way, you can see the vent rising above the level where waste should be falling. This assumes you have not clogged the line.
My suggestion would be to go with option number one. Build on the skills you have, start with a few small projects, research your tools. Read & learn about tools that will best suit your budget & room availability. Purchase tools as you need them, preferably not as you want them. You'll keep more money in the bank. And, if you make frequent moves, why buy large tools, & have to sell them to move again, or whatever the situation. You can learn & do just as much with hand tools as you can with power tools, just not as fast. For me, learning with hand tools taught me to do more quality work before I started buying power tools. I read ALOT of books on tools, their use & purposes, maintenance. Wood, jigs, whatever I could get my hands on to read to learn. You'll be a better woodworker for the time spent. JMO.
Mr. Coop, I'd like to be able to say I started out with woodworking classes in high school, & kept going from there, but I didn't. I grew up in the trucking business, & that's all I know well. Trucking is all I've ever done, that's why I read books to learn the tools, wood, how to, & all I could learn. There weren't the u tube & all when I started, & if there was, I wasn't aware of it. Like ALOT of fellers here, I'm self taught. I don't proclaim to be an expert by any means. I probably make more mistakes than anybody, but, with experience, time, & patience, I've learned to fix my mistakes. But, I also would like to think I do honest, quality work. For no bigger than our little farm community is, I've managed to build a customer base, & keep it. I'm pretty technologically illiterate, so I gave up trying to download pictures to the sites I'm involved with. My granddaughter set me up a FB page under Sawdust Haven. If you'd care to have a look see at my work, be my guest. And thanks for your comment, because I was trying to make a point with honesty, not dollar bills.
